Using Chemical Change to Identify an Unknown
If you have taught the first activity in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known...

Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Exothermic, Endothermic, and Chemical Change
Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...
